BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a building assembly system for land andwater. More particularly, the present invention relates to connectionsmade between the components and the formulation used for the moldedmulti-part polymer.

2. Background

Many families throughout the world live without access to clean water,power, waste management, sanitation and safe, sustainable homes. Poorlyconstructed communities with little to no infrastructure lock countlessfamilies into a cycle of poverty, generation after generation. To putthis into perspective, around 1.1 billion people globally have no accessto improved water supplies and 2.6 billion people lack propersanitation. More than 2.2 million people in these developing countriesdie from preventable diseases associated with lack of access to cleanwater and sanitation.

Refugee camps designed as temporary shelters are housing families forupwards of 30 years. Without proper support, these refugee communitiesscrape by in very poor conditions, unable to thrive. Two-thirds of theglobal refugee populations—over 10 million refugees live in protractedrefugee situations in thirty countries around the world.

Further, high density polyethylene (HDPE) injected with high densitypolyurethane (HDPU) foam, is not commonly thought of as a material ofuse for entire building structures. Rather, it has been known not to usehigh density polyethylene as sub-components of buildings because theinherent nature of plastic and foam was thought to be highly flammableand not structurally sound. However, high density polyethylene (HDPE) isenvironmentally stable and does not give off any harmful elements intothe environment. Products made from recycled high density polyethylene(HDPE) are considered eco-friendly because they are recyclable at theend of its useful life. High density polyethylene (HDPE) does notcontain bisphenol A, phthalates, heavy metals or allergens.

To manufacture high density polyethylene (HDPE) requires only a fractionof the energy required to produce steel from iron ore and the carbonfootprint of high density polyethylene (HDPE) production is five timeslower than aluminum. High density polyethylene (HDPE) has a largestrength-to-density ratio and its viscous and elastic characteristicprevents it from deformation and forming cracks. It also offers zerocorrosion and zero maintenance. High density polyethylene (HDPE) solidplastics are a naturally germ resistant material and can be easilycleaned since its paint-free surface will not be harmed by cleaningchemicals. High density polyethylene (HDPE) is 100% recyclable andaccepted at most recycling centers in the world because it is one of theeasiest plastic polymers to recycle.

As such, there is a need for a molded three dimensional sandwich panelmade from a thermoformed material, which meets ASTM standards. There isa need for the molded three dimensional sandwich panels to be assembledinto a self supporting habitable structure. There is a need for a fireretardant skin composition and a fire retardant foam composition. Thereis also a need for a method of manufacturing the molded threedimensional sandwich panels filled with foam.

DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

The description above and below and the drawings of the present documentfocus on one or more currently preferred embodiments of the presentinvention and also describe some exemplary optional features and/oralternative embodiments. The description and drawings are for thepurpose of illustration and not limitation. Those of ordinary skill inthe art would recognize variations, modifications, and alternatives.Such variations, modifications, and alternatives are also within thescope of the present invention. Section titles are terse and are forconvenience only.

The design of the disclosed embodiments also allows prefabricatedbuildings to be quickly deployed, relocated and reassembled as needed.The parts for the modules except for the steel structure, bolt, andwasher nut can be made from various types of polymers. Examples ofpolymers can be high density polyethylene (HDPE), high densitypolyurethane (HDPU), low density polyethylene (LDPE), linear low densitypolyethylene (LLDPE). Of course other types of materials can becontemplated. The components of the modules can be made from variousmolding processes. Example of molding process can be rotational molding(rotomolding), blow molding, injection molding, compression molding,extrusion molding, or thermoform molding. Of course other types ofmolding processes can be contemplated.

For example, according to an embodiment of the present invention, arotomolding process to produce high density polyethylene (HDPE) filledwith high density polyurethane (HDPU) foam as building components/panels(walls, roof, and floors) of the modules can be implemented. Thisprocess creates strong structures having thermal performance and thehigh density polyethylene (HDPE) with molded air cavity and injectedhigh density polyurethane (HDPU) foam provides structural integrity andoptimal thermal values. The thermal resistance properties of thecomponents/panels due to its polyurethane core creates high thermalresistance with a temperature differential from exterior to interior.For example, when the exterior temperature is about 42° C. (107° F.),the interior of the cube module 90, 100 and the triangle module 92, 102can be about 26° C. (78° F.). On the other hand, when the exteriortemperature is about −6° C. (21° F.), the interior of the cube module90, 100 and the triangle module 92, 102 can be about 20° C. (68° F.).

For the process of roto molding, the high density polyethylene injectedwith high density polyurethane (HDPU) foam is fabricated into threedimensional shapes. The structural rigidity and strength in both the Xand Y direction is created by a combination of a corner design using asingle “L” shaped column system interlocked with a tongue and groovesystem of the base, roof, and bulkhead modules and secured using bolts.Rotationally molded plastic polymer parts are assembled together withsteel framing to form a homogeneous load bearing building structure fora variety of building configurations. The molded plastic polymer partscan also be referred to as components. The high density polyethylenematerial is rotationally molded in a custom fabricated cast aluminummaster mold by a thermo-form process to create hollow plastic polymerparts.

Rotational molding comprises a heated hollow mold which is filled with acharge or shot weight of material. It is then slowly rotated bi-axially(two perpendicular axes), causing the melted HDPE to disperse and stickto the walls of the mold creating the final form.

These rotationally molded hollow polymer components are then filled witha two-step foaming process in which equipment dispenses chemical at lowpressure of about 240 psi to 250 psi. This process is nitrogen drivenwith impingement mix at the head with the option to dispense static mixthrough a mix tube on the end of the unit. The output of the gun isabout 60 pounds per minute. The temperatures at which this step isperformed is about 27-35° C. (80-95° F.) for the chemical temperature,about 27-43° C. (80-110° F.) for the substrate temp and about 37-49° C.(100° F.-120° F.) for the mold/fixture temperature. The resultant foamfilled plastic polymer parts are then assembled together to create amodule unit which are then connected to form a constructed unit 88 of aninfinite number of floor plan types.

One example of a formulation used to manufacture polymer components ofthe modules comprises intumescent flame retardant mixed with a resin. Anexample of a resin can be a high density polyethylene (HDPE) resin. Theformulation comprises about 30 weight percent of an intumescent flameretardant compound and about 70 weight percent of high densitypolyethylene resin. The intumescent flame retardant can be suitable forpolyolefin and thermoplastic elastomers such as polypropylene orpolyethylene resin. The intumescent flame retardant can be not onlymolded by injection or extrusion directly mixing with resins but alsogranulated with resin and other additives by twin screw extruder.

The intumescent flame retardant compound comprises about a 72 to 78weight percent of a flame retardant, such as melamine polyphosphate, andabout a 22 to 28 weight percent polyethylene. Preferably, theintumescent flame retardant compound comprises about 75 weight percentof a flame retardant and preferably about 25 weight percent ofpolyethylene. The resin can be high density polyethylene resin, whichcomprises about a 99 to about 100 weight percent polyethylene hexenecopolymer. The mixture of the high density polyethylene resin (HDPE) iscompounded using a high-speed twin screw compounding machine.

An example of a compound used to manufacture the foam found inside thehollow polymer components is high density polyurethane (HDPU) foam. Thehigh density polyurethane (HDPU) foam is comprised of at least twocomponents. The first component comprises about a 100 weight percent ofdiphenylmethane diisocyanate, isomers and homologues and about a 40 toabout 50 weight percent of 4, 4′-Methylenediphenyl diisocyanate. Thesecond component comprises about a 4 to 12 weight percent of a blowingagent, about less than a 4 weight percent of a catalyst, about less thana 5 percent of a flame retardant and a polyol blend. The compoundcomprises about 56 weight percent of the first component and about 44weight percent of the second component.

The structurally strong and fire retardant nature of the buildingstructure is a result of combining the buoyant nature of plastic foam,having a proper balance of fire retardant additive and creating aconfiguration geometry. The fire retardant nature of the material canslow or reduce the intensity of the combustion process. High densitypolyethylene (HDPE) is an environmentally stable plastic, giving off noharmful fumes into the environment. It also does not contain bisphenol A(BPA), heavy metals or allergens, is a naturally germ-resistant materialand offers almost no corrosion and low maintenance is required. Highdensity polyethylene's viscous and elastic characteristic preventsdeformation and formation of cracks. It is also 100% recyclable and easyto recycle.

Another process that can be used to make the components for the moduleis blow molding. There are several types of blow molding processes,which are extrusion blow molding, injection blow molding, and injectionstretch blow molding. In general, blow molding begins with melting theplastic of choice and forming the melted plastic into a parison or apreform. In the case of a parison, there is a hole in one end throughwhich compressed air can pass. The parison is clamped into a mold andcompressed air is blown into the parison. The compressed air pushes theplastic out to match the mold. When the plastic cools and hardens, themold is open and the component part is ejected.

In the example process of compression molding, the molding polymer isplaced in a preheated, open mold cavity. The mold is closed with a topforce or plug member and then pressure is applied to force the polymerinto contact with the mold surface. While the pressure is applied heatand pressure are maintained until the molding polymer has cured.Compression molding uses thermosetting resins in a partially curedstage.

In the example of extrusion molding, the plastic for the components ofthe modules is melted into a liquid which is forced through a die,forming a long tube like shape. The extrusion is cooled and forms into asolid shape. Shapes that can be formed from extrusion molding can beT-sections, U-sections, square shaped sections, I-sections, L-sectionsor circular sections. The extrusion molding process is used to createcomponents of the modules with a fixed cross-sectional profile.

In the example process of injection molding for making the componentsfor the module, the polymer is placed into a heated barrel, mixed usinga helical shaped screw and injected into a mold cavity. In the moldcavity, the polymer cools and hardens to the configuration of thecavity. Materials such as polyethylene, polypropylene, thermoplastic andthermosetting polymers. Polyethylene in different densities such as highdensity polyethylene (HPDE), low density polyethylene (LDPE), linear lowdensity polyethylene (LLDPE) can be used. The higher the density of thepolyethylene used, the stronger, more rigid the structure. The effect offire or heat resistance on the structure is dependent on the fireretardant additives. The benefits of using HDPE is that it has highlevels of ductility, has tensile strength, its resistance to impact andmoisture absorption and it is recyclable.

In the example process of thermoform molding for making component partsfor the module, the polymer sheets are heated to a pliable formingtemperature and then formed to a specific shape in a mold. When thepolymer sheet is molded, the polymer sheet is trimmed to create thecomponent part of the module. There are different types of thermoformmolding processes. One type is pressure forming where high pressure isapplied to the back side of the polymer sheet during the moldingprocess. There is also twin sheet thermoforming. In this process, hollowparts can be created by combining two polymer sheets during the moldingprocess. Another example of thermoform molding is vacuum thermoformingwherein the polymer is heated until it is formable and then draped overa mold. Once draped over the mold, a vacuum is used to pull the polymersheet to the mold, thus forming the component part.

The definition of a constructed unit 88 is any combination andconfiguration of the land cube module 90 and land triangle module 92 orany combination and configuration of the water cube module 100 and watertriangle module 102. The constructed unit 88 can comprise of at leastone land cube module 90 connected to a land triangle module 92 andtogether can be used to create a common space. The constructed unit 88can comprise of at least one water cube module 100 connected to a watertriangle module 102 and together can be used to create a common space.The land cube module 90 and the water cube module 100 can function asone independent unit.

The land cube module 90, the land trianglemodule 92, the water cube module 100, and the water triangle module 102can all be generally referred to as module.

In one embodiment of the present invention, the prefabricated modulescan use high density polyethylene (HDPE) enclosure injected withexpanding high density polyurethane (HDPU) to form a primary threedimensional assembly structure to configure into various buildingconfigurations. The prefabricated modules are complete, self-supporting,certified structures and are fire retardant to pass all regulatoryagencies as a habitable structure. The speed at which the constructedunit 88 is assembled requires only one-fourth of the total building timeof traditional methods of construction. 80% of unskilled labor and theuse of only standard tools contribute to the speed at which theconstruction system can be assembled.

The land cube module 90, land triangle module 92, water cube module 100,water triangle module 102, and constructed unit 88 are quick to assembleas standard tools and only about one-fourth of the total building timeof traditional methods of construction is required. The total powergenerated is about 21.3 kWh and the daily water supply is about 2,100liters.

There are various types of assembling and fastening pieces, generallycalled hardware, which can be used to build the modules. For example,there are trusses, straps, reinforcing posts, compression plates, andsteel leg shoes (for foundations). The hardware is made of structuralsteel and after assembly; the exposed hardware is covered with agalvanized and powder coating. These various assembling and fasteningpieces can be integrated with a steel hardware fastening system. Thereare also integrated bracket systems, also made of structural steel, forhanging cabinets, beds, storage units, and lights. An example is ahanging bracket for the wall or a hanging bracket for the shelf.
